Like the juvenile Asian carp, the goby is found in the live wells of commercial boats and can be sold as baitfish. Theses species are a threat to biodiversity because of the voracity, their ability to reproduce rapidly and their elevated risk of transporting pathogens.

The following rules apply:

The use of live baitfish is prohibited throughout the province of Québec.

The use of dead baitfish is prohibited during summer throughout the province of Québec.

The use of dead baitfish is authorized during winter in certain fishing zones in Québec where this practice was already *.

*See regulations for details.

SPINY WATERFLEA

Bythotrephes longimanus

Andrea Miehl

General characteristics:

Émily DeBolt

Small crustacean with a long pointed tail dotted with thorns.

The presence of one female is sufficient to colonize new body of water.

Reproduces sexually and asexually (clones).

Can stick to fishing lines.

Eggs are resistant to cold, dryness and even to ingestion by prey; they can be dormant during winter.

Present in some lakes in Ontario located near the border (Larder, Raven, Nipissing and Temagami lakes).

Rapid breeding and low predation rates enable this crustacean to compete directly with zooplankton and small fish.
